This milkweed is considered to be incredibly important to monarch butterflies, especially in California and other western states where it is native. Also known as Mexican whorled milkweed, it is a perfect xeric- and pollinator-garden plant with beautiful blooms that provide food and habitat for beneficial insects and many pollinators including the queen butterfly also pictured on the front of this packet. Not fussy about soil, and has high drought tolerance, though will also thrive in moist conditions. Add blooms to flower arrangements. Sap is toxic; avoid eye/skin contact and do not ingest. Perennial in USDA zones 6–10. Deer resistant.
